H2 FINAL FILTER® Extends PEM Fuel Cell Life
Sulfur compounds (primarily hydrogen sulfide, H₂S) can quickly ruin the PEM (polymer exchange membrane) fuel cells used to power buses, trucks, forklifts, and more. A few parts per billion of sulfur can make the difference between a fuel cell stack running reliably for years and one that fails catastrophically in hours.
Why is sulfur a problem?
In a PEM fuel cell, hydrogen is split into protons and electrons on the surface of the anode catalyst, usually platinum supported on carbon. Sulfur compounds like H₂S strongly adsorb on platinum, poisoning the active sites that normally split hydrogen. Even at very low levels (a few parts per billion, ppb), sulfur can block catalytic sites, causing a rapid drop in performance (current at a fixed voltage) and lead to irreversible deactivation. Commercially available ‘high purity’ H2 typically contains about 10 ppb of H2S. And sulfur absorbs weakly on the surface of most metals, so that the ‘pure’ H2 often picks up more sulfur from contaminated pipes, valves, and fittings as it travels from the source to the fuel cell stack.
While other impurities like carbon monoxide (CO) or ammonia (NH3) also impact PEM performance, sulfur is “the most important and most challenging specification to meet”1. To make matters worse, H2S magnifies the effect of CO to damage fuel cell performance. Because of this, PEM fuel cells typically require extremely low sulfur levels in the fuel. Without adequate cleanup, fuels containing even traces of H₂S can reduce fuel cell output from normal operation to zero in a short time, as was observed in this test when the filter was bypassed.
A Life-Extending New Solution: The H2 FINAL FILTER®
A new invention called the H2 FINAL FILTER, packed with the SULFUR MAGNET® changes everything. It’s a simple filter cartridge that is put near the end of the feed pipe that quietly grabs the last traces of sulfur —down to less than 200 parts per trillion (that’s like two drops in a billion swimming pools). At that level, even the most advanced sensors can’t detect the H₂S.
The SULFUR MAGNET is a regenerable, non-hazardous, high-capacity sorbent media packed into stainless-steel filter housings (the H2 FINAL FILTER® systems). It operates passively at near ambient conditions with negligible pressure drop and no utilities. Key advantages:
- Capacity up to ~55% by weight sulfur uptake.
- Removes all volatile sulfur species (H₂S, COS, mercaptans, thiophenes) plus NOx.
- Non-hazardous either before or after exposure to sulfur.
- Regenerable or recyclable, with spent media forming stable, landfill-safe compounds.
- Proven in fuel-cell and SMR testing to outperform even pure bottled hydrogen by eliminating the final traces of H2S left in the gas.
The Sulfur Challenge
The goal of the test was to see whether the H2 Final Filter could protect a small PEM fuel cell from H₂S in the hydrogen fuel stream. The test apparatus included a standard commercially available 5 cm² Ion Power PEM membrane electrode assembly operated at 80 °C and 80% humidity (typical conditions). The H2 Final Filter was placed in the hydrogen feed line upstream of the mixing point with humidified H₂. A switch valve allowed rapid switching of the fuel between (1) ‘Clean’ hydrogen (commercial high-purity H2 that typically contains 1-10 ppb H₂S), (2) ‘Dirty’ hydrogen with 5 ppm H₂S filtered by the Final Filter, and (3) ‘Dirty’ hydrogen with 5 ppm H₂S fed directly into the fuel cell.
The cell was first tested by feeding ‘Clean’ H2 fuel to the anode and air to the cathode. The fuel was then replaced with a mixture of 5 ppm H2S in H2. This setup allowed a direct comparison: the same cell, same temperature, same humidity, with and without the filter under otherwise identical conditions.
The cell was conditioned and then challenged with H₂S in a controlled way. The experimental procedure included a standard break-in period where the cell was cycled between open circuit voltage (no load) and constant voltages of 0.6 V and 0.3 V. After conditioning, in step (1) the cell was held at 0.6 V for 5 hours on ‘clean’ hydrogen fuel while monitoring the current to establish a stable baseline and confirm that the cell behaved normally with clean gas. With the cell still at 0.6 V, in step (2) the fuel was switched to hydrogen containing 5 ppm H₂S, but with the H2 Final Filter in place. It was operated under these ‘filtered dirty fuel’ conditions for 25 hours, and the current output (with voltage fixed at 0.6 V) was monitored. After 25 hours, in step (3) the cell was switched from filtered fuel to unfiltered 5 ppm H₂S (bypass line, no filter) and the current was again monitored at the same 0.6 V, to see how quickly the cell degraded when
sulfur reached the anode.
Figure 1 presents the record of the current produced by the PEM fuel cell under the 3 conditions described above. With the ‘clean’ fuel (1) the current was measured at about 1.4 amps which is typical performance for this type of cell. In step (2), when the cell was fed H2S containing fuel that had been cleaned by the H2 Final Filter, the current remained unchanged at about 1.4 amps. The H2 FINAL FILTER completely removed the sulfur and protected the platinum anode against sulfur poisoning. When fuel containing 5 ppm H2S was allowed to enter the cell (3) the current dropped precipitously and continued to degrade irregularly for another 25 hours. After the cell had degraded under unfiltered H₂S, the fuel was switched back to ‘clean’ fuel to see whether the performance would recover, but no recovery was observed, indicating irreversible damage had occurred.
Polarization curves are like ‘fingerprints’ of the condition of the cell. Cell polarization curves (current vs voltage) were recorded after operation for 5 hours on clean fuel and after 25 hours of operation on contaminated fuel filtered by the H2 FINAL FILTER; they are compared in Figure 2. Polarization curves taken after operation with clean fuel and after operation with contaminated fuel cleaned by the H2 FINAL FILTER were essentially indistinguishable. There was no measurable negative effect on cell performance attributable to gas passing through the filter over the ~30 hours tested (5 hours clean fuel + 25 hours filtered dirty fuel). A post-test polarization curve after exposure to unfiltered 5 ppm H₂S could not be obtained because the cell had degraded due to sulfur poisoning of the platinum anode to the point that it could not provide meaningful output.
Significance for PEM fuel cell applications
1. Protection from low-level sulfur is essential.
The fact that 5 ppm unfiltered H₂S completely killed the cell, with no recovery, highlights that typical PEM fuel cells cannot tolerate even a few ppm of sulfur in their fuel. Any real-world system using fuel that may contain sulfur (from reformers, industrial gas sources, pipeline gas, etc.) will require effective sulfur cleanup.
2. The Final Filter can provide robust protection
During 25 hours of continuous feed with 5 ppm H₂S in the H2 fuel that is cleaned by the H2 Final Filter, the cell performance was indistinguishable from operation on ‘clean’ hydrogen. This proves that the H2 Final Filter can remove sulfur to levels that are harmless to the PEM anode.
Where this matters in practice
The implications of these results differ by application and by fuel quality.
1. Fuel-cell systems using high-purity hydrogen (e.g., cylinders, well-controlled industrial sources), that are typically already low in sulfur (1-10 ppb), can be
protected against poor-quality gas and can have their useful lives extended. The benefits include risk reduction and cost savings.
2. Systems that use hydrogen from reformers or mixed-fuel processing (SMR, poor-quality ATR, gasifiers) often contain 100+ ppm of sulfur that conventional desulfurization may reduce to the ppm range. The H2 FINAL FILTER could be placed downstream of the primary cleanup system to ensure that the fuel entering the PEM stack is effectively sulfur-free, greatly extending stack life.
3. Backup power and stationary systems intended for remote or industrial sites see more variable fuel quality. A robust sulfur filter provides resilience
against fuel quality swings. The H2 FINAL FILTER is a relatively simple hardware addition that prevents sudden stack loss due to unanticipated sulfur spikes.
4. High-value, high-uptime applications (data centers, telecom, critical infrastructure, semiconductor manufacture) where the cost of losing a stack or batch of product is very high would be protected by the H2 FINAL FILTER.
This test included a real, commercially relevant PEM fuel cell generating electricity from hydrogen and air that showed no impact of sulfur in the feed when the H2 FINAL FILTER was in place; that is the difference between normal operation and a total stack replacement.
H2 FINALFILTER® Enables Clean Energy
The H2 FINAL FILTER with the SULFUR MAGNET technology represents a step change for PEM fuel cell users. The H2 FINAL FILTER:
- Completely prevents sulfur poisoning of a PEM fuel cell even when the incoming fuel contains significant concentrations of H₂S.
- Allows the safe processing of opportunity feedstocks with higher or variable sulfur content, such as biogas
- Delivers hydrogen meeting the most stringent fuel-cell purity specifications (ISO 14687 Type D/E) without additional purification steps
By eliminating trace sulfur — the primary life-limiting factor in a PEM fuel cell — the H2 FINAL FILTER has the potential to accelerate The Hydrogen Economy while maximizing the value and sustainability of PEM fuel cell vehicles already in service and enabling further adoption of fuel cell technology. PEM fuel cells will be fueling vehicles for decades to come, and the SULFUR MAGNET is helping to pave the way to a low-carbon, clean-energy future.

FINALFILTER® Protects Steam Reforming Catalysts
Steam methane reforming (SMR) is the quiet giant behind modern life. This straightforward process — mixing cheap, abundant natural gas with steam at high temperature over a nickel catalyst — produces about 75% of all the hydrogen man made on Earth today.
That hydrogen is essential for:
- Producing the fertilizer needed to grow half the world’s food
- Cleaning gasoline and diesel to reduce air pollution
- Manufacturing plastics, pharmaceuticals, margarine, windshield-washer fluid, and thousands of other everyday chemicals
- Powering fuel cells for cars, trucks, backup generators, and stationary power plants to electrify
The nickel catalysts inside these giant reformers are amazing at their job, but they are incredibly fussy about sulfur. Even a tiny whiff of hydrogen sulfide (H₂S) — think a few drops in an Olympic swimming pool — can slowly “poison” the catalyst and force expensive shutdowns.
Natural gas usually arrives with a few parts per million of sulfur compounds (like the smell you notice when there’s a gas leak). Conventional hydrodesulfurization plus zinc oxide guard beds routinely reduce this to < 0.1 ppm (100 ppb), which is already very clean. However, over months of operation the damage builds: activity drops, methane slip rises, coke forms, tubes overheat, and eventually the plant faces an expensive shutdown to replace the catalyst. It’s the number one reason reformers don’t last as long or run as efficiently as they otherwise could. For the very best catalyst life and for super-sensitive fuel cells, the sulfur concentration needs to be less than 1 part per billion — and that last little bit is surprisingly hard and costly to remove.
A Game-Changing New Solution: The FINALFILTER®
A new invention called the FINALFILTER, packed with the SULFUR MAGNET® changes everything. It’s a simple filter cartridge that is put near the end of the feed pipe that quietly grabs the last traces of sulfur —down to less than 200 parts per trillion (that’s like two drops in a billion swimming pools). At that level, even the most advanced sensors can’t detect the H₂S.
The SULFUR MAGNET is a regenerable, non-hazardous, high-capacity sorbent media packed into stainless-steel filter housings (H2 FINAL FILTER® systems). It operates passively at near ambient conditions with negligible pressure drop and no utilities. Key advantages:
- Capacity up to ~55% by weight sulfur uptake.
- Removes all volatile sulfur species (H₂S, COS, mercaptans, thiophenes) plus NOx.
- Non-hazardous either before or after exposure to sulfur
- Regenerable or recyclable, with spent media forming stable, water insoluble landfill-safe compounds.
- Proven in fuel-cell and SMR testing to outperform even pure bottled hydrogen by eliminating the final traces of H2S left in the gas.
A Remarkable Demonstration
Now imagine deliberately feeding to an SMR test unit gas that contains far more sulfur than it could ever survive long-term— enough to kill the catalyst in hours — and observing rock-steady performance because the Final Filter removed the very last traces of H₂S.
That is exactly the bold experiment a leading fuel-cell company ran on their work-horse laboratory SMR unit — the same reformer they rely on every day to turn ordinary natural gas into hydrogen for testing their latest fuel-cell stacks. The SMR catalyst activity is determined by monitoring the CH4 conversion.
The experiment was run in four crystal-clear phases shown in the Figure:
- “Clean gas”: The SMR unit was operated in its baseline conditions on normal bottled CH4 gas (typically desulfurized to < 0.1 ppm by conventional systems),
- “H2S through Sulfur Magnet” The sulfur challenge: 50 ppm H₂S was added to the bottled CH4 - a level that poisons the catalyst – and the catalyst activity was monitored while the H2S containing gas is passed through the SULFUR MAGNET. Methane conversion efficiency stayed rock-solid at fresh-catalyst levels for the entire 100-hour run.
- “H2S by-passed filter” The H2S-containing gas bypassed the FINALFILTER and was fed directly into the SMR unit so that the catalyst is rapidly poisoned.
- “Clean gas” The SMR unit was returned to its initial operating conditions without the FINALFILTER and severely reduced activity due to the irreversible sulfur poisoning of the catalyst that was observed.
The SULFUR MAGNET didn’t just slow the poisoning — it prevented it completely, even under sulfur concentrations that would rapidly cripple the reformer without it.
This was a real, production-style SMR unit converting methane to the hydrogen that powers cutting-edge fuel cells — deliberately challenged with failure conditions — but perfectly protected by a simple, passive filter that finally eliminates the industry’s oldest Achilles’ heel.
FINALFILTER® Enables a Cleaner Future
The FINALFILTER with the SULFUR MAGNET technology represents a step-change for SMR and downstream hydrogen users. The Final Filter:
- Protects reformer catalysts indefinitely at sub-ppb sulfur concentrations to extend primary reformer catalyst life far beyond current industry averages
- Allows the safe processing of opportunity feedstocks with higher or variable sulfur content, such as biogas
- Delivers hydrogen meeting the most stringent fuel-cell purity specifications (ISO 14687 Type D/E) without additional purification steps
By eliminating trace sulfur — the primary life-limiting factor in steam reforming —the SULFUR MAGNET has the potential to accelerate The Hydrogen Economy while maximizing the value and sustainability of existing SMR infrastructure and enabling new processes. Hydrogen has been feeding and fueling the world for decades, and the SULFUR MAGNET is helping to pave the way to a low-carbon, clean-energy future.
Killing Pathogens in Wastewater
Comparing Chlorine Dioxide and the SULFUR MAGNET® MULTIFUNCTIONAL MEDIA®
BOTH KILL: Bacteria, Funguses, Parasites, and Viruses on contact
CHLORINE DIOXIDE (ClO2) is a highly reactive yellow-green gas that cannot be transported due to health, safety, and environmental concerns; it must be generated at the point of use. It is highly toxic to humans, animals, and pollinators. While effective for disinfection, chlorine dioxide forms byproducts like chlorite and chlorate, which pose health risks. Chlorine dioxide has a short effective lifespan (minutes) and poses an explosion hazard since it decomposes quickly in sunlight or with organic materials. It is ineffective against odors in water and is a single-use material. Chlorine dioxide's hazards - ranging from acute irritation and toxicity to chronic developmental and potential carcinogenic effects - and limited effectiveness in cleaning water, outweigh its benefits.
SULFUR MAGNET® MULTIFUNCTIONAL MEDIA® is a highly porous granular media that has no DOT restrictions on transporting the virgin or spent media because it is not flammable, 100% VOC free, insoluble in water, and can be handled with only gloves and dust masks. It has the capacity to absorb roughly half its weight in noxious chemicals and a great tenacity for removing odors from water, unlike activated carbon that easily releases the trapped odors. Since the SULFUR MAGNET® does not decompose upon use, it can be used repeatedly without being replaced, and its active lifespan is measured in years, not minutes, when used in water with a pH of 6 or higher.
Solid Oxide Fuel Cell Testing - A Game Changer for Fuel Cells
Standard H2 has developed a revolutionary, patented system called the SULFUR MAGNET® that removes sulfur from gas streams to concentrations below 1 ppb. This breakthrough technology is a game-changer for gas cleaning needs for any process where sulfur poisoning occurs, such as fuel cells and catalysts, as well as for general air-purification systems. A recent demonstration using a commercially relevant fuel cell system shows its startling impact on fuel cell performance, which will be a welcome relief to the fuel cell industry.
A study was conducted by solid oxide fuel cell developer Nexceris that dramatically shows the ability of the SULFUR MAGNET® to improve fuel cell performance. The experimental results presented in the Figure on page 2 show that with a fuel containing 10 ppm H2S, the SULFUR MAGNET® was able to remove the sulfur such that the performance of the cell matched its performance with the high-purity H2 feed. The experiment was conducted as follows:
An anode-supported Nexceris fuel cell was tested at 700 °C with a high-purity hydrogen feed at a current density of 0.5 A/cm2. After a few hours, the cell came to a steady state voltage of 0.836 volts. The cell was operated under pure H2 with negligible degradation (25 mV/1000 hours) for an additional 15 hours to establish the baseline.
At the 20-hour on-stream mark, the hydrogen feed was directed through a cartridge of the SULFUR MAGNET® before entering the fuel cell. No change in performance was observed as the voltage was steady at 0.835 volts.
The feed was then switched to one containing 10 ppm of H2S in hydrogen that was passed through the SULFUR MAGNET® before it entered the fuel cell. The results are nothing short of remarkable.
After about 80 minutes of conditioning during which the cell voltage dropped to as low as 0.826 volts, the performance almost magically rose not merely to the previous steady state level of 0.835 volts, but to a maximum of 0.838 volts. The cell with a sulfur-containing feed that had been scrubbed with the SULFUR MAGNET® was outperforming the cell with what was believed to be pure hydrogen.
The cell was operated for an additional 15 hours under conditions of 10 ppm H2S in H2 cleaned by the SULFUR MAGNET®. During this time, the degradation of performance was about 44 mV/1000 hours, nearly the same as that measured for the pure H2 during the baseline.
Finally, the SULFUR MAGNET® was removed from the system, and the unfiltered sulfur-containing H2 feed was admitted to the fuel cell. A rapid decline in the cell voltage was noted, and after about 3 hours, the cell performance had declined to 0.748 volts, where it appeared to approach a new steady state.

As demonstrated in this test, the SULFUR MAGNET® provides a point-of-use system to remove H2S from hydrogen from any source, since even H2 produced by water electrolysis picks up trace contaminants during handling on its journey through pipes and regulators. A small cartridge placed immediately upstream of a fuel cell or other device can protect it from sulfur contamination for many thousands of hours, depending on the level of sulfur in the gas and the gas flow rate.
Work at Standard H2 continues to evaluate other uses of the SULFUR MAGNET® for the removal of trace contaminants from gas and liquid streams. For sulfur removal, the global market for solid adsorbents like the SULFUR MAGNET® is estimated at over $600 million, with about $100 million related to fuel cells. Other applications include protective masks, semiconductor manufacturing, and catalyst guard beds.
General Solution Overview
- Cleaning hydrogen to remove the volatile sulfur compounds that ruin the efficiency and shorten the lifetime of H2 Fuel Cells by reducing the sulfur concentration to below 1 ppb .
- Removing the oxides of nitrogen, H2S, etc. from air and the air intake side of the fuel cell.
- Cleaning natural gas to remove H2S and thiols that corrode boilers, heat exchangers, etc.
- Cleaning biogas for renewable natural gas.
- Trapping NOx at high temperatures such as in diesel exhaust (400+C) or power plant flue gas (700+ C)
- Catalyst guard bed protection.
- Cleansing the bottled gases used in labs and high-tech instruments.
- Cleansing the gases used during computer chip manufacture, etc.
- Cleansing water to remove H2S and other contaminants for H2 electrolysis.
- Cleaning potable and waste water by removing H2S, forever chemicals, etc.
- Odor removal from arenas and breeding facilities of show animals.
- Gas masks to remove H2S, NOx, halides, foul odors (skunk, etc.).
Here’s why sulfur elimination is our specialty:
SAE J2719:2020 “Hydrogen Fuel Quality for Fuel Cell Vehicles” sets the standard. For volatile sulfur compounds the maximum concentration is 4 ppb, the lowest of all contaminations because the 100% correlation between the concentration of catalyst poisoning sulfur and the lifetime and efficiency of the catalyst.1 This US Standard is very similar to the EU standard.
There is a direct negative relationship between sulfur content in hydrogen (H2) and the lifetime of a catalyst; higher sulfur content in the hydrogen significantly reduces the lifespan of a catalyst due to a phenomenon called "sulfur poisoning," where sulfur compounds bind to the active sites of the catalyst, inhibiting its ability to facilitate reactions effectively.
Key points about sulfur poisoning and mitigation:
- Mechanism:
Sulfur-containing molecules like hydrogen sulfide (H2S) readily adsorb onto the active sites of a catalyst, blocking other reactants from accessing those sites and hindering the catalytic process. Even small amounts of sulfur can significantly decrease the activity and selectivity of a catalyst, leading to a decline in product yield. - Feedstock purification:
Removing sulfur compounds from the hydrogen feedstock before it reaches the catalyst is the most effective way to prevent sulfur poisoning.
Hydrogen is the Solution to Global Climate Change: This is the Missing Link to the Hydrogen Economy
THE FACT IS: THERE IS NO SHORTAGE OF HYDROGEN, PRICE IS THE PROBLEM
#1 Steam Methane Reforming, SMR, accounts for roughly 95% of H2 production and is, by far, the least expensive way to mass-produce hydrogen with no or minimal production of CO2. For decades, hydrocarbon refiners have produced hydrogen for sweetening crude oil, and to make inexpensive commodity chemicals like ammonia and urea. Fuel Cells are the backbone of the hydrogen economy and require much cleaner hydrogen with the lowest possible sulfur content.
#2 Hydrogen Fuel Cells efficiently convert hydrogen and oxygen into electricity and clean water, but the catalysts used in H2 Fuel Cells are expensive and very easily damaged by hydrogen sulfide, H2S, and other volatile sulfur compounds in the hydrogen. Sulfur impurities greatly reduce the lifetime and efficiency of H2 Fuel Cells; reducing the impurities by half will double the lifetime, and a 75% reduction will quadruple the lifetime, etc. for a HUGE impact on ROI and CO2 avoidance.
#3 Current H2 standards are lax because no inexpensive sorbent is currently available to purify the hydrogen below the EU standard of 4 ppb sulfur content in the H2 at the pumping station . The US goal is 1 ppb maximum sulfur content. EVEN WORSE, as H2 sits in the storage tank and as it travels through the pipes to the fuel cell, it can pick up impurities so that when it reaches the fuel cell it will not be as pure as when it was put in the storage tank. For a similar reason, fuel filters are always used just before the engine on conventional vehicles. FUEL CELLS NEED SIMILAR PROTECTION!
HERE’S THE SOLUTION: CLEAN low grade HYDROGEN to LOWER THE PRICE and MAGNIFY ROI STANDARD H2, INC. HAS THE MISSING LINK: The SULFUR MAGNET® can reduce sulfur to below 200 ppt from any source of hydrogen. The H2 FINAL FILTER® contains the SULFUR MAGNET®, the most powerful inexpensive sulfur sorbent known to remove the catalyst killing sulfur compounds with its tenacious and high-capacity composition of non-toxic non-water-soluble granules. Use this to reduce the sulfur content to below 1 ppb and place it just before the fuel cell intake to MAGNIFY the ROI of H2 Fuel Cell ownership! Perhaps even better, the SULFUR MAGNET® is transported with no DOT restrictions for the virgin or spent media, and the media is regenerable, easily recycled, or can be land-filled with no fear of contamination because the SULFUR MAGNET® is not a combustible sponge like activated carbon, it is a stable chemical trap.

Pure Electrolytic Hydrogen with the SULFUR MAGNET® and the H2 FINAL FILTER®
H2 Fuel Cells rely on ultra-high purity hydrogen for efficient operation and long life for a high ROI. The catalysts used in fuel cells are expensive and easily damaged by volatile sulfur compounds such as hydrogen sulfide (H2S). Unfortunately, the current paradigm uses electrolysis to produce hydrogen with by-product H2S that can contaminate the integrity of the H2 Fuel Cell, which reduces their efficiency and total lifetime.
Make electrolytic hydrogen pure the easy way using as SULFUR MAGNET® water filter to remove sulfur from the water input to the cell and a H2 FINAL FILTER® filled with the SULFUR MAGNET® placed on the electrolytic cell’s output H2 line. The SULFUR MAGNET® is the most tenacious, inexpensive, non-toxic sulfur sorbent for cleaning water, hydrogen, and other fluids. An independent third party found it reduced H2S from 1.902 ppm to under 200 ppt, the limit of detection. This is much cleaner than the current World standard of 4 ppb and would dramatically raise the ROI of H2 Fuel Cell ownership.
Reducing the sulfur content to 1 ppb would quadruple the efficiency and lifetime of the fuel cell. Hydrogen is the CO2 avoidance solution to stop global climate change and Standard H2, Inc. has the inexpensive solution to make the highest purity hydrogen from any source.
The SULFUR MAGNET® is available for removing volatile sulfur compounds from most gases and most liquids. Please refer to the SDS for additional details.

Expand Your Return on Investment (ROI) with the H2 FINAL FILTER®
H2 Fuel Cells rely on efficient operation and ultra-high purity hydrogen for a high ROI. Catalysts used in fuel cells are expensive and easily damaged by volatile sulfur compounds such as hydrogen sulfide (H2S). Unfortunately, the current paradigm uses electrolysis to produce hydrogen with by-products that can contaminate the integrity of the H2 Fuel Cell, which reduces their total lifetime.
H2 Final Filter, Inc. manufactures the SULFUR MAGNET® and recommends using a H2 FINAL FILTER® placed in-line and as close as possible to the fuel intake to remove impurities in the fuel gas, the fuel line, and the fuel tank. Petroleum-powered vehicles have fuel filters located just before the motor for the same reason.
Fortunately, the SULFUR MAGNET® is the most tenacious sorbent of contaminants for cleaning hydrogen and other fluids. An independent third party found it reduced H2S from 1.902 ppm to under 200 ppt, the limit of detection. This is much cleaner than the current World standard of 4 ppb and would dramatically raise the ROI of H2 Fuel Cell ownership.
Hydrogen is the solution to stop global climate change via CO2 avoidance. And Standard H2 , Inc. has the inexpensive solution to make the highest purity hydrogen from water and methane without CO2 production.
Decarbonization by Steam Methane Reforming and the SULFUR MAGNET®
Hydrogen is the solution to stop global climate change via CO2 avoidance. Standard H2 , Inc. has the inexpensive solution to make the highest purity hydrogen from water & methane without CO2 production.
The hydrocarbon refining industry already makes the most hydrogen and does it cheaply by reacting H2O (water) with CH4 (methane) making 3 molecules of H2 and one of CO. This process known as Steam Reforming, or the Steam Methane Reforming (SMR) process makes no CO2. This is not high-grade H2 because their need is to hydrogenate crude oil, make urea, and make ammonia, which do not require pure H2.
However, they could produce vast amounts of ultra-high purity hydrogen by using the SULFUR MAGNET® to polish their production of H2. With the largest methane reserve in the World, the USA could easily become the World’s #1 source for clean hydrogen.

What is Steam Methane Reforming (SMR)?
SMR is the primary method for hydrogen production in the U.S. The process uses high-temperature steam to convert methane, typically from natural gas, into hydrogen, carbon monoxide, and a small amount of carbon dioxide.
CH4 + H2O → CO + 3H2
The hydrocarbon refining industry already uses SMR to generate unpure H2. However, implementing the SULFUR MAGNET® into our industries would generate pure H2. With the largest methane reserve in the world, the USA could easily become the world's #1 source for clean hydrogen.
